I would like someone to explain, somewhere that I can find it again, how scientific or botanical names are written - what's in italics, what's in quotes, and what has the first letter in upper case and what doesn't. I just almost missed an entry for Photinia in Straley's Trees of Vancouver book because it was listed separately in the index from Photinia. I'm guessing that means something, though maybe it's just that the second entry was a common name and it was just an indexing peculiarity, but a tree listed only in the first entry is what I know by that common name. To continue with my question, for instance, the italic baccata in Taxus baccata is a different sort of indicator from the not italic brevifolia in Taxus brevifolia? For extra credit, does x indicate a naturally occurring hybrid? And the x is not italic, but what follows it is in italic lower case? How is that different from var., which is not italic, but what follows it is italic and seems it could be upper case or not? A link to where this has already been fully described (online, so I can find it again) will be fine. I know I tripped over something like this in the past 6 months, but I have no idea where and the search words don't seem to be occurring to me.
